86-01: Comprehensive Drift Measurements on a Circular Mechanical Draft Cooling

Comprehensive drift measurements were made on multiple cells of a circular crossflow mechanical draft-cooling tower. The data include both Isokinetic mineral mass flux determinations and liquid droplet flux and sizing determinations using a sensitive paper methodology. Cell to cell variations are presented along with the results of repeatability measurements. Additionally updraft air velocity and waterflow measurement results are provided. The importance of specific ambient mineral concentration measurements vis–vis cooling tower exit plane concentrations is discussed in concert with data on five tracer elements. Data from this tower are presented and compared with those of other towers that were also subjects of comprehensive drift measurements programs.
